You need to find the surface area with the formula for calculate the surface area of a rectangular prism:

$SA=2(wl + lh + hw)$

Where w is the width, l is the length, and h is the height.

You can observe in the figure that:

$l=5cm\\w=4cm\\h=2cm$

Then, substituting the values into the formula $SA=2(wl + lh + hw)$ , you get that minimum amount of cardboard used for the wrapper is:

$SA=2[(4cm)(5cm)+(5cm)(2cm)+(2cm)(4cm)]\\SA=76cm^2$
